Highlights: Good (Tidal) Beach Reading

Tide-dominated
beaches are widespread in today's world, and coastal researchers have recently
begun to address their sedimentary character, finding that they differ notably
from the more familiar, purely wave-dominated beaches. Nonetheless, ancient
tide-dominated beaches are infrequently recognized, perhaps for want of
suitable sedimentological criteria and facies models. Smosna and Bruner present
the facies reconstruction of The Cambro-Ordovician Cabos Formation of northern
Spain, a system interpreted to represent an ancient tide-dominated beach
system. In describing sedimentologic observations and the criteria on which the
interpretation is based, this analysis constitutes a beginning step in
constructing the sedimentological framework for a virtually unknown (or at
least poorly documented) paleoenvironment.
